Every free student calculator in one place: CGPA to percentage by university rule, SGPA tools, target CGPA planner, attendance calculator and more. No ads, no signup.

All calculators

Free • No ads • No signup • Nothing stored

Every calculator on CGPA to Percent in one place. The conversion tools apply your university's own official rule — taken from its official document and linked with every result — while the planning tools (target CGPA, attendance) use the standard semester arithmetic explained on their pages. Everything runs in your browser: no ads, no trackers, no signup, and your marks are never stored or sent anywhere.

Conversion calculators

Start with the CGPA to Percentage calculator if a form asks for a percentage, or the Percentage to CGPA calculator for the reverse. Students of specific universities can go straight to their pre-selected page: SPPU, Anna University, AKTU, GTU, MAKAUT, Delhi University and CBSE Class 10. The CGPA to Percentage Chart puts every official rule's table side by side.

Semester calculators

Build a CGPA from semester results with the SGPA to CGPA calculator (simple or credit-weighted, with a running breakdown), calculate one semester from subject grade points with the SGPA calculator, or convert a single semester with the SGPA to Percentage calculator. University SGPA pages with credit notes exist for VTU, KTU, SPPU, JNTUH, JNTUK, SRM, Mumbai, Calcutta and Calicut in the footer.

Planning tools

The Target CGPA planner works out the average SGPA you need in your remaining semesters, and honestly tells you when a target is no longer reachable. The Attendance calculator shows your current percentage, how many classes you can safely miss, or how many you must attend in a row to recover to 75%. The Marks Percentage calculator converts marks obtained into a percentage, and the CGPA to GPA calculator gives an indicative 4.0-scale estimate for study-abroad shortlisting — clearly labelled indicative, because foreign universities convert transcripts their own way. The SGPA Trajectory Chart graphs your semester SGPAs together with your cumulative CGPA line, and the Placement Cutoff Checker tests your CGPA against a percentage cutoff (like the common 60%) using your university's own official rule.

Why these tools are different

Most conversion sites quietly apply one memorised multiplier to everyone, including formulas universities have repealed. Here, every rule is taken from the university's own official document, scoped to the scheme or batch it governs, linked from the result, and dated with when we checked it. If we cannot verify a rule from an official source, the tool refuses to invent a number.

Frequently asked questions

Are these tools free?

Yes — every calculator on this page is free, with no ads, no signup and no data stored. Calculations run in your browser.

Which CGPA to percentage formula do the tools use?

Each university's own official published rule, linked from every result. If a university has not published a formula we can cite, the tool says so instead of guessing.
